Seems so simple but there is a bit to think about.

Let me set it straight. Correct me if I'm wrong on any of these.

All of these are ZL1 swapping into an SS fuel pump.

ZL1 pump swap with no tune. Pump will run same as stock pump. No more flow/pressure?

ZL1 pump swap with tune? More flow/pressure?

ZL1 pump swap with a BAP and no tune? What will the BAP do at this point?

ZL1 pump with tune and BAP? Should be about 50% more flow.

ZL1 swap with FPCM swap and tune? Obviously the best but is it more flow than the BAP?

Obviously all are WOT full run.

I wish I knew what exactly the FPCM was benefiting. If Lingenfelter uses a KB BAP with it then it must be pretty decent.

NO, not at 800 crank power but surely 700?

What does this mean?

Zl1 pump in stock SS: modest increase in flow. Not pressure.
Zl1 pump with module and no tune: same as above.
Zl1 pump without module and tune or no tune: same as above.
Zl1 pump with module and tune: the ADM module allows PWM modulation of the pump to increase flow and pressure as demand increases, as in the factory application.
ZL1 pump with BAP: the BAP increases VOLTAGE with a boost reference internal to the BAP.

Damn. Quick response. I appreciate it.

Well I guess I may do a module but first try and see if the BAP keeps up.

ZL1 pump is already in and BAP is already there so I should have some good flow once tuned. If not I"ll do the ADM module. There is another one out there too that my builder told me about.

JMS Powermax fuel pump booster.

The ZL1/BAP will probably flow more than a ZL1/ADM module combo. I've never personally seen a ZL1 pump with both a module and BAP. I'm definitely not saying it is really a big deal, but some I have dealt with were concerned with pump life at the higher voltages produced by the BAP, so the module is an option for those people.

ADM FPCM, when car is tuned for it, boosts pressure at 4K rpm and above. It is a modified ZL-1 FPCM. Without the tune, it behaves like an OE FPCM with no benefit.

There were numerous threads with HPT logs that show fuel pressure increases. I use the ZL1 pump, ADM FPCM, and KB BAP. KB BAP w/OE SS pump, couldn't keep up fuel pressure at 10 PSI boost with my KB 2.8. Mine was dropping to 48-49 PSI. Left the BAP since it was pre-wired in the trunk. Added the pump and FPCM and everything is good. Not planning to go over 650 RWHP, the suggested safe limit.

Longer life is no big deal to me because I cut the access panel. It's literally a 25 minute job to swap.

Do you mean you couldn't keep up BEFORE the ZL1 pump.

That's where I was dropping to the same 45 to 49 pressure before. But I'll have more power now. Not sure how much. I'm guessing about 100 hp crank.

I cut a panel also. What are you estimating your total power to be at? And at what boost pressure?

I'm thinking 12 psi and somewhere around 750 crank power.

That's a really rough estimate.

Before the cam failed it was 8.5 psi boost with a bit smaller cam and I've lowered the compression by .2:1 so I'm only guessing at the power level.

Before it was 560 whp 560 wtq. so around 650+ crank power.

You should be good. You just need the fuel setup to provide enough fuel to provide about 70 psi of rail pressure and enough volume for your motor. The ZL1 pump and BAP should do that.

Upper boost/RPM ranges, KB BAP could not keep up. Can't remember, but recall kit deka 60lbs running somewhere around 75-80% duty cycle. Idle and low rpm drive ability sucked. But that's a different story. Didn't want to constantly R&R so went with ID1000, too. I believe the duty cycle is in the 50ish range now and Fuel pressure is solid. Probably, injectors helped, too. The stock kit parts wasn't optimal. Should have gone tuner kit instead. Live and learn...

The old thread OP was using an MSD BAP. Not bad for around $500 for fpcm and pump. Otherwise, dual FP or squash for higher HP requirements.

im right at 68-70 psi with zl1 pump adm, fpcm, 60 percent duty cycle, with 60 lb injectors, without having to run bap.

I'll be using 85# injectors so not worried about that end but I suppose I'll see what happens.

So a zl1 pump + zr1 map=650rw capability?
Tuned for it of course.

Only with the ADM module. As I said above, it's the module that gives MAP referenced fuel pressure increase above 58 psi(stock) rail pressure. The tune is to change the stock module limits to the new fuel flow/pressure limits of the module.

I'm 400.00 richer! The through the back seat pump install was the easiest install I have done yet.. but the scariest! on the back hole I drilled to allow the air snips to enter the bit grabbed and went in far! But no problem! there was alot of room no scratch or ding! on the front hole be careful though its close! I just lifted the rear seat cushion didnt even have to remove it. I timed my self it took 32 min. 10 min of that was looking for a longer punch!

SO ZL1 pump imstalled..

BTR cam pos displacement stage 3 and GMHP CNC heads going on THursday!

What will the speed shop do for fuel you guys think? BAP ADM Boosta pump? I asked them and they said they needed to see where the car was at.. I like to buy and bring my parts my self I like to shop around get free ship and tax..

They will be installing the Cam, pushrods, Springs, ID 850s, Heads, Smaller Pulley, and Granetelli wires.

If you don't mind me asking, what type of cam failed on you?

Those injector size come with a supercharger kit? I have a tvs2300,anyone know what size injectors those come with? Planning on buying an ADM fpcm.

I'm not sure why those injectors are so small.. there useless if you do any other motor work like cam, heads, and smaller pulley! I hate buying stuff twice! the kits should come with 85Lbs or higher for E85.. or atleast a upgrade option so your not stuck with them!

That's why the tuner kits are available, they don't include.the injectors or the handheld that you wouldn't need if you were doing other work.

Magnacharger uses those injectors because they are cheap from GM since they are a production injector.
